how to load video from android_asset

[lee11qian]

react-native-cli: 1.0.0
react-native: 0.36.0
react-native-video: 0.9.0

i want to use like this:

<Video source={{uri: 'file:///android_asset/source/64.mp3'}} .../>

but logcat tell me:

Failed to open file '/android_asset/source/64.mp3'. (No such file or directory)

I guarantee that the file exists.

Can't it be used in this way.

I hope someone tell me how to do.

I might be wrong, but according to this SO

MediaPlayer expects an URI and it's impossible to create an URI for an assets file

Seems like you need to use AssetManager to get file descriptor to the video file and set it as datasource for MediaPlayer. But if you look at the file ReactVideoView.java, it doesn't support it.

So maybe not possible to load from android_asset. You could however just use React Native asset system as mentioned in the Readme.

Or pull request? 😄

Thank you for tell me this. But my project must use file from android_asset. So i change the file ReactVideoView.java like this:

if (uriString.startsWith("content://")) {
    Uri parsedUrl = Uri.parse(uriString);
    setDataSource(mThemedReactContext, parsedUrl);
} else if (uriString.startsWith("file:///android_asset")) {    // <----- add begin
    AssetFileDescriptor afd = getResources().getAssets().openFd(uriString.replace("file:///android_asset/", ""));
    mMediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
    mEventEmitter.receiveEvent(getId(), Events.EVENT_LOAD_START.toString(), null);
    prepareAsync(this);
    return;                    // <----- add end
} else {
    setDataSource(uriString);
}

Is it any errors? I just use it in my project now.

Does this still work? Can this be a PR and merged?
I also need to use uri: 'file:///android_asset/ because the videos are large and the code-push would delay a lot.

How can we do this now? In 2020?
